Treatment as a State Actions on Tribal Lands in EPA's South Central Region
Treatment as a State Under the Clean Air Act
Pursuant to Section 301(d) of the Clean Air Act (Act), the U.S. Environmental Protection Agency makes determinations of eligibility for the tribe to receive 'Treatment as a State' (TAS) in the implementation of certain elements of the Clean Air Act. When a Tribe desires to receive TAS for specific elements of the Clean Air Act, they must make application, EPA must review, the public may comment, and ultimately the EPA may grant the request made by the Tribe. This page lists the TAS CAA actions and associated documents for Tribes requesting or that have requested such designation in Region 6.
One may search for all TAS actions that are open for public comment, including those in EPA Region 6 at the website: Public Notice at U.S. EPA
All documents related to a specific request may be accessed by clicking one of the hypertext links associated with the applicant's name in the table below.
